3. Safety precautions

All warnings in the manual are summarized on thispage.

Pay special attention to the instructions below so thatsevere personal injury and/or damage to the valveare avoided.

Safety

- Always read the technical data thoroughly (seepage 36).

- Always fit the seals correctly.- Always release compressed air after use.- Always remove the CIP connections, if supplied,

before service.

- Never service the valve when it is hot.- Never pressurise the valve/actuator when the valve

is serviced.

Never stick your fingers through the valve ports if theactuator is supplied with compressed air.

Never touch the clip assembly or the actuator pistonrod if the actuator is supplied with compressed air(see the warning label).

Always supply compressed air carefully and turn theactuator away from the personnel when removingupper piston (7) (51-101.6 mm/DN50-100 only).

Always counterhold at the end of the tool spindle whenreleasing the actuator spring as the actuator spring (9)is not caged (51-101.6 mm/DN50-100 only).


- Always release compressed air after use.- Never touch the clip assembly or the actuator

piston rod if the actuator is supplied with com-pressed air (see the warning label).

Never stick your fingers through the valve ports if theactuator is supplied with compressed air.


- Never touch the clip assembly or the actuatorpiston rod if the actuator is supplied withcompressed air (see the warning label).

- Never pressurise air connections (AC1, AC3)simultaneously as both valve plugs will be lifted(will cause mixing).

Never touch the valve or the pipelines when pro-cessing hot liquids or when sterilizing.

Always handle lye and acid with great care.

- Never throttle the leakage outlet.- Never throttle the CIP outlet, if supplied.

Installation

The instruction manual is part of the delivery.Study the instructions carefully.

CIP = Cleaning In Place (see page 10).Fit the warning label supplied on the valve afterinstallation so that it is normally visible.

Check the delivery for:1. Complete valve.2. Delivery note.3. Warning label.

1. Unpacking/Delivery

CAUTION!We cannot be held responsible for incorrect un-packing.

Avoid damaging the air connections, the leakageoutlet and the valve ports. Avoid damaging the CIP connections, if supplied.

Remove possible packing materials from thevalve ports.

Removepackingmaterials!

Inspect the valve for visible transport damages.

2. Recommended auxiliary equipment (DN125-150) - Hoist

The valve sizes DN125-150 are very heavy.Therefore Alfa Laval recommends manufacturingand usage of auxiliary lifting equipment. A proposalis given below.

In addition to the auxiliary equipment shown below asmall lifting crane should be used.Please note that the auxiliary equipment cannot besupplied by Alfa Laval.

Hoist:- The purpose of the hoist is to make lifting

and handling of the valve easier, as thevalve sizes DN125-150 are very heavy.

- The hoist consists of three hook rods and arod for crane which are fastened to a flangewith four nuts and three self-locking nuts.

- To avoid dropping the valve during lifting,the hoist must be made with the correctmeasurements (see 3 and 4). All measure-ments are in mm.

Operation:1. Position the hoist around the actuator/bonnet.2. Place crane hook under rod for crane.3. Make sure all three hook rods are

positioned under the actuator/bonnet.4. Lift the valve.

Trestle:- The purpose of the trestle is to support the

valve during dismantling and reassembly.- The trestle is made of a base plate, two

support plates, two rubber linings and fourbolts.

- The rubber linings are attached to thesupport plates so that the valve/actuator willrest on these.

- To prevent the valve from turning duringdismantling and reassembly the trestle mustbe made with the correct measurements(see 3, 4 and 5). All measurements are inmm.

Always install the valve vertically.

- Always read the technical datathoroughly (see page 36).

- Always release compressed air afteruse.

- Never touch the clip assembly or theactuator piston rod if the actuator issupplied with compressed air (see thewarning label).

CAUTION!- Fit the supplied warning label on the valve

so that it is normally visible.- We cannot be held responsible for incorrect

installation.

Ordering spare parts

- Contact the Sales Department.- Order from the Spare Parts List.

Recommended spare parts: Service kits (see Spare Parts List).

The valve is designed so that internal leakages donot result in the products becoming mixed.Internal leakage in the valve is externally visible.Study the instructions carefully.

Always keep spare rubber seals and guide rings instock.Check the valve for smooth operation after service.

(*) All products wetted seals

Pre-use check1. Supply compressed air to AC1, AC2 and AC3 one

by one.2. Operate the valve several times to ensure that it

operates smoothly.Pay special attention to the warnings!

Lower seat-lift adjustment (only sizes 51-101.6 mm/DN50-100):1. After total assembly of the valve, check that washer

(2) on the top of the actuator piston rod (10) can bemoved. If necessary, loosen the nut (1).

2. Tighten the nut gradually until the washer (2) canbe moved just slightly and upper piston rod (10)moves 2-3 mm when supplying compressed air toAC3.

NOTE!If the nut is tightened too much, in order to increase theCIP flow during lower seat-lift, the lower plug might notclose completely and there is a risk of leakage.

NOTE!For large sizes, DN125-150, only item 1 and 2 applies.
